IPC: G07F19/00
Filed: 2007-12-24
Abstract: A method for compensating a sensor automatically is provided to prevent an erroneous operation of the sensor by controlling a current level of a light emitting device according to a slice level after resetting the slice level when the contamination of the sensor is removed. A sensor signal is measured through a sensor input unit and is converted to a digital value after entering an initialization mode(S606). A digital value about the stored existing sensor signal, a presently set current level of a light emitting device, the digital value about the sensor signal of a light receiving device, and the minimum slice level, and the maximum slice level are loaded(S608). The digital value about the loaded existing sensor signal is compared with the digital value of the sensor signal measured through the sensor input unit. If the compared value is different, a new slice level value is produced and the slice level is changed according to the produced slice level value(S614). If the changed slice level is lower than the minimum slice level, the current level of the light emitting device is decreased to the minimum level(S620). After a new slice level value is produced by converting the sensor signal into the digital value, the maximum slice level is compared with the new slice level value(S624). If the slice level value is lower than the maximum slice level, the slice level is changed by the digital value of the newly measured sensor signal(S628).
